IMPROVEMENT IN LAMPS.

Specification forming part of Letters Patent No- 221,078. dated October28, 1879; application filed July 19, 1879.

To all whom it may concern Be it known that I, WILLIAM O. LINCOLN, ofBridgeport, in the county of Fairtield and State of Connecticut, haveinvented certain new and useful Improvements in Lamps, of which thefollowing is a specification.

This invention consists in the combination, in a lamp, of a base-piece,a supporting-rod extending from the center of it, ahorizontalcylindrical reservoir provided with a slide or socket extendingtransversely through its center fitting upon said supporting-rod, meansforv securing the said reservoir in different vertical positions on thesaid rod, a burner arranged upon the reservoir at one side but in linewith its slide or socket, and provided with a shade-holder and shadereceiving within them the rod aforesaid, the whole being so organizedthat the reservoir and its appurtenances may be turned relatively to therod without changing its balance, and hence without danger of tippingover.

In the accompanying drawings, Figure l is a side view of a lampembodying my invenignates a horizontal cylindrical reservoir providedwith a slide or socket, S, fitting on the rod B, and extendingtransversely through its central portion and somewhat below it, where itis provided with a clamping-screw, D, for securing it and the reservoirin different vertical positions.

- The reservoir, as represented, is furnished on one side of theslide'or socket S and rodB with a filling-mouth, E, fitted with a removable screwcap, and on the other side with a burner, G, which is in linewith the slide or socket S, and supports a shade-holder, H, and shade I,within which the rod B extends.

A lamp having its reservoir thus centrally supported .over the center ofits base-piece,

and the burner at one side of the supportingrod, so that the latter willbe received within its shade-holder and shade, while it affordsprovision for concealing the supporting-rod, is susceptible of havingits reservoir and appurtenances turned around said rod without entailingthe danger of tipping the lamp over,

and hence is far superior in appearance and equal in convenience to theordinary studentlamps.

I am aware that it is not new to provide the reservoir of a lamp with aslide or socket extending transversely through its center, and arranginga burner on it .at one side in line with the slide or socket, andcombining said reservoir with a supporting-rod extending from the centerof a base through the slide or socket of the reservoir.

I am also aware that it is not new to provide a reservoir with anexternal slideway on one side and support it by a supporting-rodextending eccentrically from a circular base-- piece up into a shadeapplied to the-burner of the lamp.

In the latter lamp the reservoir, and consequently the burner, could notbe adjusted around the supporting-rod so as to shed light in anydirection without endangering the tipping over of the whole lamp, andtherefore is objectionable.

I-do not elaun either of the above constructions as of my invention.

What I have in view is to make a compact lamp having the abovecharacteristics, and one wherein the supporting-rod extends up throughthe shade-holder into the shade of the lamp, the whole being soconstructed that the reservoir and its appurtenances may be turned uponthe supporting-rod without danger of tilting the lamp, which I regard asnew and original with me.

What I claim as my invention, and desire to secure by Letters Patent,is-

The combination, in a lamp, of a base-piece, a supporting-rod extendingfrom the center of it, a horizontal cylindrical reservoir provided witha slide or socket extending transversely through its center fitting uponsaid supporting-rod, means for securing the said reservoir in differentvertical positions on the said rod,

a burner arranged on the reservoir at one side tions on thesupporting-rod Without endangerhut inline with the slide or socketthereof and ing the tilting of the lamp, substantially as provided witha shade and shade-holder respecified.

ceiving within them the supporting-rod, the \VM. 0. LINCOLN. whole beingso organized that the reservoir Vitnesses: and its appurtenances may beturned and ad L. M. SLADE,

j usted and secured in different vertical posi- \V. U. MARSH.
